Cover from Italy

This is my first cover from Italy where bird stamps are used.  It is also my first registered cover from that country.  The set on it was issued in 1995.
Grey heron (Ardea cinerea): It can be found in some parts of Africa and in temperate Asia and Europe.  In the colder areas it is migratory.  It has four subspecies.  It feeds on frogs, fish, insects, reptiles, small mammals and other birds' chicks.
Griffon vulture (Gyps fulvus): This bird of prey lives in Asia, north Africa and southern Europe.  It can be found in Cyprus too.  In the wild it can live for 50-70 years.  It is a scavenger.
Golden eagle (Aquila chrysaetos): I already presented it on a stamp from Algeria.
White-winged snowfinch (Montifringilla nivalis): This species of sparrow can be found in southern Europe and western and central Asia.  It has four subspecies.  It feeds on seeds and insects.
